Updates avrftdi to use libftdi1

This includes adding libftdi1 to configure.ac and Makefile.am.
avrftdi code is changed to use libftdi1. At the same time device
discovery is moved to libftdi1. Some error and debug messages in
avrftdi are corrected and/or updated. avrftdi_print is updated,
to print all messages whose verbosity level is less or equal to
the global verbosity level, so that messages with level 0 are always
printed.
This change is tested on OS X 10.6.8, Ubuntu 12.04.2 and Win7 x86_64.
The Win7 version was cross-compiled on OS X 10.6.8.
